Edexcel Biology A Paper 2 - 16th June 2023 [Exam Chat]

paper 1 was alright, but not happy about the lack of human bio

also is it just me or is anyone much less confident on topic 7 and 8; im not just revising the content, im learning it ugh

Same, tbf topic 7 and 8 are the things we have never really encountered back in GCSEs. they're whole new worlds

How did it go for everybody ?

It took me by surprise. I didn't revised for 1-4 at all and they didn't put that many topic 7,8 questions

omgg frr??? i acc hated it. and someone tell me where the hell lac operon came from i dont remember learning that at all

It's a small part in topic 3, transcription factors

it’s topic 3 i think, due to transcription factors. The lactose binds to a respressor so the gene can be activated and transcribed by RNA polymerase on the promotor region. The enzyme b-galactosidase breaks down lactose into galactose and glucose.

Trueee ...cant believe the 13 marker was on cardiovascular diseases when they couldve done so many other topics ..i didnt revise for 1-4 either 😭

It was too many info in the last question. Also if you drink AlCohOl, your risk of CVD dEcrEaSes...
